Need Help with Configuration Files

I just uploaded some configuration files onto the Duet Wifi courtesy of another user that has the same printer. While it was uploading via the web interface, the server crashed. I was unable to access it through wifi and pronterface. I suspect it has to do with one of the files that I uploaded. I then proceeded to reset the firmware through sam-ba and was successful in doing so. Afterwards, there were no problems connecting to pronterface and no problems invoking M503 to check on the config file. The problem arises when I invoke M552 S1. It says wifi starting, but hangs pronterface. I let it run for a few minutes and it still does not work. As mentioned above, this happened when I uploaded an entire sys folder into the board. Anyone have the stock configurations of the sd card so that I can effectively get a stock "new" board? Thanks
